The window shade web is provided with a traction rod, which is moved at both ends by means of drive members along the guide rails. A compensating device is provided to compensate assembly tolerances or shape tolerances, which assures that too great tensions extending parallel with the windup shaft do not occur in the window shade web, which would lead to obliquely extending waves in the extended window shade web.

Description

The rolling-up car window sun-shading screen of tape wrapping compensation

Technical field

The unique distinction of modern automobile vehicle body shape is that the vehicle window area is bigger.Because sunlight is strong,, with regard to the automobile that has air-conditioning,, produces excessive heat and can cause inconsiderable energy usage in order to offset the calorific effect in the car so bigger vehicle window area causes at the sizable heat of the inner generation of car.

Background technology

For this reason, automobile has been equipped rolling-up car window sun-shading screen more and more.

Thus, well-known be at the window side to two guide rails are installed, wherein guide the end of the draw bar of vehicle window sun screen paper web.The length of draw bar can be regulated, can adapt to different window breadth.Actuating is to be undertaken by the insert that moves on guide rail.

This insert has only the very large power of expense fully to regulate, thereby they make the motion of vehicle window sun screen draw bar accurately be parallel to the furling type sun screen.If the shortage parallelism then can skew the paper web of this vehicle window sun screen, cause the ripple that oblique extension on the paper web of the vehicle window sun screen that launches, occurs.This is plain and can not achieve the goal.

Summary of the invention

For the foregoing reasons, the objective of the invention is to create a kind of rolling-up car window sun-shading screen that is used for automobile, wherein the inaccuracy of insert is regulated the distortion that can not cause vehicle window sun screen paper web.

According to the present invention, this purpose is to realize by the rolling-up car window sun-shading screen with feature as claimed in claim 1.

The normal position occurring departing from is that this distance and the normal active distance that requires are variant because be used to make the actuator and the spool of draw bar motion that one segment distance is arranged basically.The Another reason of the crooked pulling of vehicle window sun screen paper web is owing to draw bar, and it does not just extend according to the normal position and the accurate together coefficient result of actuator who regulates from initial.

For example, if actuator turns round with insert, and under the effect of motor, move, only acting on this draw bar pulls out vehicle window sun screen paper web, if and an insert is leading, make draw bar depart from its normal position thus, i.e. the position that under the situation of rear window, for example extends in parallel with vehicle window sun screen paper web, to on vehicle window sun screen paper web, produce uneven tension force so, and cause ripple to form.

Because actuator and gear motor interlocking one are worked, the problem of draw bar dislocation and adjusting aspect itself has increased.Thus, the dislocation of a tooth pitch between two actuators, can occur almost reaching, be almost 3～6 millimeters amount in actual use.Add the production tolerance of vehicle window sun screen paper web.Because sawing and cutting error, this draw bar error just occurs with respect to spool parallelism itself.

If these error minus stacks, 10mm even bigger error are not impossible so.Formed like this dislocation causes producing oblique stress on vehicle window sun screen paper web, causes the oblique extension ripple or the fold of vehicle window sun screen paper web.

When equally, mentioning side window substantially also similar situation can appear.But, always be in obliquity at this draw bar with respect to spool, that is, at the normal place draw bar with respect to the oblique extension of spool.If this moment, traction piece moved in the mode of dislocation, and force the physical slot that changes draw bar, so also will cause ripple to form.

Automatically guaranteed that according to compensating device of the present invention draw bar the dislocation of corresponding standard position (inclination or parallel) occurs breaking away from and reaches the degree that reduces at least, and on vehicle window sun screen paper web, do not caused tangible ripple to form.

Compensating device like this has several possible basic solutions in principle.

According to a solution, the spool of vehicle window sun screen paper web is bearing in one itself can be in the spider of lateral axis with the limited manner swing.

This axis of longitudinal extension part with respect to spool preferably is in the center.Therefore, this spool can self-control, makes draw bar remain on normal place with respect to spool.

Except spool is supported in the spider, if an end bearing of spool in one can limited pivotally supported fixed type bearing in, or the inclination that makes spool can carry out appropriateness is moved, and this spool can be done free motion significantly with respect to a plane that is limited by vehicle window sun screen paper web that is parallel to expansion in another bearing simultaneously, also can realize same purpose.

For tolerance balancing error on both direction, this spool is equipped with opposite inclination in rest position certainly.

This bearing is preferably fixed, and also is used as the anchoring device of actuating device of the spring simultaneously.If provide a slotted hole for another bearing hole in this case then be enough to, the gudgeon of bearing is bearing in wherein in movable mode.

At last, another actual selection of determining the compensating device position comprises spring installation is arranged between actuator and the draw bar.Because the power that its elasticity, this spring installation have reduced to appear at the draw bar two ends and cause ripple to form is poor.

The guide piece of vehicle window sun screen paper web of the present invention preferably includes the guide rail that wherein includes guide groove.

This guide groove can be used to guide insert simultaneously, prevents its kink.

If spool is offset to the direction that vehicle window sun screen paper web is rolled by means of actuating device of the spring, driver train becomes simple especially so.In this case, when motor and actuating device applied power to draw bar, spool was forced to move along with the motion of vehicle window sun screen paper web.

The vehicle window sun screen can comprise weaving material or porous or dyeing film.

With regard to the window that its surface is not rectangle, the length of draw bar is adjustable, and purpose is to change with the distance between the guide rail of continuous variation.

Other embodiment of the present invention also are the themes of dependent claims.Directly do not provide example embodiment for those, its comprehensive characteristics also is considered as included within the claim.

The specific embodiment

In the diagram, Fig. 1 shows the back view of a car 1, has roof 2, boot 3 and two C t shores 4 and 5.Rear hatch 6 is between two C t shores 4 and 5, and its top is the boundary with the trailing edge 7 of roof, and the below is the boundary with the root edge 8 of rear window.Back window glass for example is bearing in the rear hatch 6 by the window rubber strip is bonding in a well-known manner.

Rear window shelf 9 is positioned at the inside of car 1, is in the place ahead of rear window, and it is horizontal-extending between the backrest of vehicle window lower edge 8 and back seat, cannot see in the drawings.The exit slot 11 of one wire extends on rear window shelf 9.

Exit slot 11 is parts of rear window furling type sun screen 12, and its basic structure very schematically is shown among Fig. 2 with lateral plan.

Rear window furling type sun screen 12 has two guide rails, it and then two C type posts 4 and 5 fix along the lateral margin of rear hatch 6.Owing to be diagrammatic cross-sectional view, so in Fig. 2, only can see a guide rail 13 that for example is fixed on the C t shore 5.

Guide rail 13 has shape of cross section as shown in Figure 3.Its cross-sectional plane is the square of band fillet substantially, and with antetheca 14, two side 15 and 16 and rear wall 17 be the boundary.The fastening flange 18 of one strip extends from rear wall 17, is connected on the suitable position of vehicle body by means of this flange guide rail 13.

In guide rail 13, include cross-sectional plane ringwise and by the guide groove 19 of slit 21 at antetheca 14 openings.

Guide rail 13 is made by for example extruded aluminium section.

Because the size of slit 21 is narrower than the diameter of guide groove 19 ring sections, so form a groove of the notch, it is suitable for preventing the kink of wire insert, by suitable cross-sectional plane, prevents that the insert with suitable diameter from passing slit 21 arrival outsides.

Guide rail 13 changes its gabarit with window edge, and can not see from vehicle window with respect to several axis bendings.The arrangement form of guide rail 13 is to make the opening of groove 19 on mutual opposed direction.

As shown in Figure 2, guide rail 13 extends downwardly under the rear window shelf 9 by slit 11.

As shown in Figure 4, spool 23 rotary way are bearing in the supporting spider 22.

The supporting spider 22 that is used for supporting shaft 23 is the U-shaped structure, two

legs

25 and 26 that it has a posterior elements 24 and extends with the right angle from it, and wherein spool 23 supports with rotary way by suitable bearing spigot.

Bearing spigot 27 is positioned at the center of posterior elements 24, and its axis extends with the right angle with respect to the axis of spool 23.Bearing spigot 27 is bearing in the bearing hole 28 of support 29, and support 29 is securely fixed on the car under rear window shelf 9.Like this, spool 23 can rotate, and is subject to the axis that bearing spigot 27 is limited.

Midway location, promptly the position of centering is limited by two

springs

31 and 32, and an end bearing of spring is on supporting spider 32, and the other end is bearing on the bearing 33, and this bearing is fixed on the vehicle body and just and schematically shows.Two

springs

31 and 32 are bearing on the point of transition of posterior elements 24 and

respective leg

25 or 26, thereby produce the moment of torsion that equates.

Spool 23 is a tubulose, and puts an actuating device of the spring 34 interior.Actuating device of the spring 34 comprises a helical spring, and the one end is fixed on the inside of spool 23, and the other end is fixed on the supporting spider 22.

Vehicle window sun screen paper web 35 be shaped as the trapezoidal shape approximate with the gabarit of rear window 6, the one edge is fixed on the spool 23.Edge away from spool 23 forms a hose-like ring 36, wherein is supported with draw bar 37.Draw bar 37 comprises a fixed size pipe, wherein inserts two L

shaped guides

38 and 39 from two ends, as shown in Figure 5.

Guide 38 comprises a long foot 41 that can move in the fixed size pipe, and comprises with L shaped structure leg 42 at an angle.Leg 41 mates with the cross-sectional plane of fixed size pipe, and its size makes it can arrive the inside of corresponding guide groove 19 by slit 21.But leg 42 is the cross-sectional planes with guide groove 19 circular portions to be complementary.Like this, leg 41 can vertically move in the fixed size pipe, and leg 42 can move along corresponding guide groove 19.It can not laterally be pulled out from slit 21.

Guide 39 has in the identical structure of guide 38, so the explanation of opposite side can be omitted.

Driver train 45 very schematically is shown in Fig. 5, and it is provided is in order to launch vehicle window sun screen paper web 35.For reduced representation with make easy to understand of the present invention, the two lateral guide rails of representing with the cross section in Fig. 5 13 have rotated a direction, make two guide grooves 19 point to people with the aid of pictures.As described, it only is for easy to understand that this figure is provided.In practice, the opening of two guide grooves 19 is relative, is not to point to people's direction with the aid of pictures.

Gear motor 46 is parts of driver train 45, is made up of permanently excited Direct Current Motor 47 and gear case 48.Two

guide grooves

49 and 51 are parallel to each other, and are in the gear case, provide output gear 38 between it on output shaft 52.Output shaft 52 links to each other with output gear and is fixed together not have and relatively rotates, and by output shaft, output gear 53 is rotated at both direction.

Conduit 54 extends to the lower end of the guide groove 19 on the right guide rail 13 from guide groove 49.At left end, guide groove 51 links to each other by the lower end of the guide groove 19 on conduit 53 and the left rail 13.

One flexible

elasticity wire insert

56 or 57 extends by guide groove 49 and by guide groove 51.Insert 56,57 part of not using separately back in the storage pipe that guide

groove

49,51 other end separately extends.

Two inserts 56 are consistent with 57 structure.Comprise an elastomeric flexible inner core 58 separately, one or more ribs 59 are arranged in its outside, constitute single head or multiple screw thread at this place.Rib 59 is radially outstanding on whole cylinder core 58, and from an end of insert to other end spiral extension.Output gear 53 has the tooth that can enter between the groove that rib 59 constituted.Like this, output gear 72 and

insert

56 and 57 mutual interlock couplings.

The operating mode of described rear window furling type sun screen is as follows:

In dead position, spool 23 turns to the position that vehicle window sun screen paper web 35 is rolled by the effect of actuating device of the spring 34.In this position, hose-like ring 36 is positioned at exit slot 11, as shown in Figure 2.

Guide

38,39 is positioned near the lower end of two guide rails 13, but leg 42 is not deviate from corresponding guide groove 19 and 21.

Simultaneously insert 47 and 57 two ends are spaced apart with corresponding leg 42.

If, begin from this position of furling type rear window sun screen 12, be not subjected to any obstruction into the car at this position light, the user may want to make shaded effects, and he can launch vehicle window sun screen paper web 35 so.Vehicle window sun screen paper web 35 has reduced entering of light, but is not to stop fully.For this purpose, vehicle window sun screen paper web 35 usefulness colors are that for example open chain fabric of black is made, or make with plastic film.

For launching vehicle window sun screen paper web 35, can make gear motor 46 runnings, to insert 56 is rotated by the direction that guide groove 19 moves right.Because two

inserts

56 and 57 are in antipodal two ends and output gear 53 engagements, so insert 57 is promoted left by the guide groove 19 of left rail 13 simultaneously.After a bit of distance of advancing, the lower end engages of the leg 42 of two

inserts

56 and 57 free end and guide 38 and 39, and in further process, promote

guide

38 and 39 to direction towards the upper end of two guide rails 13.

Because the distance between the guide rail changes, guide 38 and 39 leg 41 are nested in the fixed size pipe that is included in the draw bar 37 in the corresponding ring 36 simultaneously.

In case the arrival end position, gear motor 46 stops.The end position that launches is shown in Fig. 5.

Gear motor 46 is self-lockings, and insert 56 and 57 is trapped on its corresponding in-position.

Closing by means of limit stop switch of gear motor 46 finished, or guide 38 and 39 extends to and prop up retaining means, produces the blocking-up electric current, and an electronics package is judged it, and motor cuts out.

Vehicle window sun screen paper web 35 is fixed between draw bar 37 and the spool 23 with tensioning state now.

For backrush, then gear motor 46 beginnings are rotated in the opposite direction, make two

guides

56 and 57 break away from corresponding guide rail 13 and move downward.Draw bar 37 moves downward simultaneously, because this vehicle window sun screen paper web 35 keeps tensioning by the effect of the actuating device of the spring 34 of spool 23 always.

Because the structure of rolling-up car window sun-shading screen 12, draw bar 37 have the normal place (position at an angle) of the structure of being subjected to domination with respect to spool 23.Tension force in the vehicle window sun screen paper web 35 is in the direction at right angle, no matter has how many vehicle window sunshade paper web 35 to pull out from spool 23.Shown in the situation of furling type rear window sun screen under, the normal place that is subjected to the structure domination position parallel that be draw bar 37 with spool 23.

It is consistent that the position of the shape of vehicle window sun screen paper web 35 and

insert

56,57 is subjected to the normal place of structure domination therewith.

Because the tolerance of shape, it is inaccessible being subjected to the normal place of structure domination, only can be with the normal place of reality for it.

Insert

56 and 57 build-up tolerance make the

insert

56,57 can not be according to the normal place that is subjected to the structure domination with respect to spool 23 motions; An insert will always move in another front.The resultant effect of shape tolerance and build-up tolerance causes draw bar 37 apart from physical slot displacement more or less.Vehicle window sun screen paper web has counteraction to this displacement, therefore as not taking at measure, in vehicle window sun screen paper web 35, will produce tension force, this tension force is with respect to the oblique extension of the longitudinal axis of spool 23, and 37 its physical slots of disengaging enter stressed position because

insert

56,57 is propulsive draw bar.

But, because spool 23 pivotally support by supporting spider 22, thus spool 23 can be on limited extent oblique aligning, and so with the actual position of draw bar 37, promptly insert 56,57 position that forces draw bar 37 to enter is consistent.The tension force component that horizontal expansion can not be arranged in vehicle window sun screen paper web 35.Therefore be at least weakened since the position of draw bar 37 with according to the not corresponding effect that produces of the normal place of shape.

Spider 22 is biased in the position of centering by means of two springs 31 and 32.Prevented to make a sound at the click click that the driving process moves and therefore produces around the transverse axis inclination.

Reduce to break away from its physical slot or make its another kind that tilts to move the tensile stress that produces select to be shown in Fig. 6 owing to insert 56,57 rotates draw bar 37.

Wherein be supported with as shown in Figure 4 the spider 22 of spool 23 except adopting, in the embodiment according to Fig. 6, the right-hand member of spool 23 is fixedly supported upon in the fixed bearing block 61, as seen in FIG..The fixed end of actuating device of the spring 34 is being bearing in this place.But, bearing spigot, invisible among Fig. 6, with respect to spool 23 certain inclination amount of movement is arranged.

Another bearing seat 62 is fixed on the vehicle body, is positioned at the other end, is fastened on the bearing arrangement of vehicle with its leg 62 and suitable fastener hole 64.Another leg 65 of bearing seat 62 is positioned at spool 23 vertically extending planes.One slotted hole 66 is arranged on this leg 65, hold with rotary way and receive the corresponding bearing spigot 67 of spool 23.The long axis of slotted hole 66 extends along the parallel plane direction that cardinal principle and the vehicle window sun screen paper web of launching 35 are limited.

Bearing spigot 67 can be from the other end that very freely moves to slotted hole 66 in abutting connection with the position of leg 63 shown in the figure.In order to make this motion become possibility, the other end of spool can correspondingly tilt mobile in bearing seat 61.

In dead position as shown in Figure 6, spool is positioned at the other end of slotted hole, corresponding to the minimum favourable tolerance of matching between shape tolerance and the build-up tolerance.So with this disadvantageous pairing, insert, for example insert 57 under any circumstance always at first contacts with direct guide 38 in abutting connection with slotted hole 66 or bearing seat 62 contacts.

Because the guide function of slotted hole 66, and the other end quite firmly is bearing in the bearing seat 61, spool 23 can slight inclination, and can make by this way and himself adapt to the position of draw bar 37, promptly because the effect draw bar 37 of two inserts is forced to the present position.

In an illustrated embodiment, it is far away more that insert 57 motions surpass insert 56, and bearing spigot 67 (with respect to the position among Fig. 6) in slotted hole 66 promotes many more.Avoided to a great extent because the horizontal expansion tension force that the asymmetric extension of draw bar 37 causes.

In the aforementioned embodiment, spool 23 is around lateral axis pivoted with limitation correspondingly.Under the situation according to Fig. 4 embodiment, this lateral axis is in the center of the longitudinal extension section of spool 23, and in the embodiment shown in fig. 6, it extends by a bearing spigot of the end of spool 23.

But it also is possible providing needed tolerance compensating with the fixed supported form of spool.A kind of for example as shown in Figure 7 solution can be used for this.

If have big difference, then in vehicle window sun screen 35, produce horizontal tractive at the both sides of vehicle window sun screen 35 two

inserts

56 and 57 power that produce.Provide spring installation 71 according to Fig. 7, eliminate this big difference.

Fig. 7 has provided the amplifier section of one of two guide rails 13, the mutual action between expression its

respective insert

56,57 and corresponding guide 38 or 39.One spiral compression spring 71 is bearing in the blunt nosed end of

insert

56,57 and is between the corresponding blunt nosed end of leg 42 of L type bent angle.Both sides at rolling-up car window sun-shading screen 12 are all arranged like this.

If insert 56 is in different distances with 57 two working ends with

corresponding guide

38,39, this species diversity compensates by spiral compression spring 71 so.At the little some place of distance, the compression of spiral compression spring is slightly larger than opposite side.Although produced different slightly power thus, on given diff-H, with there not being spiral compression spring 71 to compare, its value is little.

The power extent is the function of the length and the spring curve characteristic of spiral compression spring 71.According to this embodiment, be necessary to be determined by experiment the length of spring 71 and the equilibrium value between the static permission power difference.

Can not cause tangible ripple in the vehicle window sun screen paper web 35 medium and small power differences of launching.

One rolling-up car window sun-shading screen has a spool and vehicle window sun screen paper web fixed thereon.This vehicle window sun screen paper web provides draw bar, its at both ends by actuator along guide rail movement.Provide compensating device compensation assembly error or shape error, guarantee in vehicle window sun screen paper web, not appear at cause oblique extension ripple in the vehicle window sun screen paper web of expansion cross hightension with spool extends in parallel.
